In March 2026, jdx/mise delivered a targeted lockfile reliability improvement: when updating an existing lockfile that is a symlink, the update now resolves the symlink and updates the target file instead of replacing the link. The change includes tests confirming correct symlink behavior and updates the lockfile-saving logic to modify the target, enhancing stability for users relying on symlinked lockfiles. This work reduces risk of breaking setups and strengthens the reliability of dependency management in Mise.
